St. Louis is slogging through a cloudy, soupy start to Saturday, with temperatures stuck near 70°F and scattered downpours sliding across parts of the metro. The wet wake-up may slow some drives, but the bigger story is that the weekend ends on a seriously hot note.
Morning Showers
Showers and thunderstorms are likely before 10 a.m. Saturday, July 25, with the afternoon high near 88°F and a light south wind around 5 mph. Any stronger storms could dump brief heavy rain, leaving roads slick and putting an extra drag on the morning commute.
Dangerous Heat Sunday Into Monday
Once today’s storms move out, the heat cranks up fast. A Heat Advisory is in effect from 11 a.m. Sunday, July 26 through 9 p.m. Monday, July 27, with highs near 95°F on Sunday and around 99°F on Monday and heat index values topping 105 6110°F in parts of the metro. Residents are urged to take extra precautions, stay hydrated, and limit midday exertion, according to the National Weather Service.
Cooling Options And Safety
If you need a cool place to ride out the heat or help with utilities, you can call 2-1-1 or 1-800-427-4626. Cool Down St. Louis also operates a hotline at 314-241-7668 for assistance. For details on local cooling centers and related services, check with United Way 2-1-1.
Plan Ahead
Try to schedule outdoor plans for early morning or later in the evening and keep water handy. If possible, push heavy physical work into the cooler hours. Heat stroke is a medical emergency: if someone is confused, fainting, or has very hot skin, call 911 right away and move them to a cool place while you start cooling them down.
